Your set up is one of the cleanest I have seen on a 80
That being said the cross over set up like Booger's the one that you point out is what I envision when I mentally dissect other set ups.
Thanks bud, and likewise! Here's another picture that might be helpful with regards to 'true high-steer'. As you'll notice during full turn/full stuff, the tierod comes very close to the pitman arm. Now you can imagine what would happen if you had the tierod mounted on top of the steering arm. You'd lose quite a bit of uptravel in order to make it work. On my setup I'll use the full travel from a 14" coilover.
